STS 1609-3

STS 1609-3 Shrink Tunnel

The STS 1609-3 is a compact industrial shrink tunnel designed to produce consistent, professionally finished shrink packages. Its PID temperature controller maintains accurate heat settings, while the variable-speed live-roller conveyor controls package exposure time. Therefore, operators can balance temperature, airflow and conveyor speed for different products and shrink films.

Additionally, the STS 1609-3 uses a recirculating convection-air system and adjustable blower control to distribute heat throughout the chamber. High-efficiency stainless steel heating tubes provide dependable heat generation, while protective heat guards help shield operators from hot machine surfaces.

STS 1609-3 Benefits

• PID temperature control supports consistent operating temperatures.
• A variable-speed conveyor adjusts package dwell time.
• Conveyor speeds reach up to 98 feet per minute.
• Adjustable blower velocity helps refine shrinking performance.
• Recirculated convection air distributes heat throughout the chamber.
• Stainless steel heating tubes provide efficient heat generation.
• Teflon mesh rollers support smooth package movement.
• Heat guards provide additional operator protection.
• A compact footprint simplifies packaging-line integration.
• The 16.5-inch-wide chamber accommodates products up to 14.5 inches wide.

How the STS 1609-3 Works

First, a compatible sealer encloses the product inside shrink film. Next, the conveyor carries the loosely wrapped package into the heated chamber.

Inside the tunnel, stainless steel heating tubes generate heat. Meanwhile, the recirculating-air system moves heated air around the package. As a result, the film contracts evenly around the product.

Operators can adjust the temperature, conveyor speed and blower velocity to match the package and film. Finally, the conveyor moves the finished package out of the heated chamber for cooling, handling or downstream packaging.

STS 1609-3 Package Capacity

The STS 1609-3 accommodates packages up to 14.5 inches wide and 9 inches high. Additionally, its internal chamber measures 39 inches long, 16.5 inches wide and 9 inches high.

Because the published capacity does not list a maximum product length, package length should be evaluated according to conveyor spacing, film type and required heat exposure. Consequently, sample testing can help establish the correct settings for long, lightweight or temperature-sensitive products.

The tunnel’s maximum conveyor speed reaches 98 feet per minute. However, actual production speed depends on the package dimensions, film characteristics, tunnel temperature and desired shrink quality.

STS 1609-3 Specifications

Actual production output depends on product size, film formulation, conveyor speed, temperature settings and spacing between packages.

Standard STS 1609-3 Features

The STS 1609-3 includes PID temperature control and a variable-speed live-roller conveyor. Therefore, operators can adjust both the chamber temperature and package dwell time.

Additionally, the tunnel features Teflon mesh conveyor rollers and high-efficiency stainless steel heating tubes. A recirculating convection-air system distributes heat, while the adjustable blower control changes airflow intensity.

Heat guards provide added protection around exposed hot areas. Furthermore, the compact frame helps the tunnel fit into production areas where floor space remains limited.

Adjusting the STS 1609-3 Shrink Tunnel

Temperature, conveyor speed and airflow work together to determine the finished package appearance. For example, increasing conveyor speed reduces the package’s time inside the heated chamber. Conversely, decreasing the speed increases heat exposure.

Film gauge and formulation also affect the required settings. Therefore, operators should begin with the film supplier’s recommendations and then make gradual adjustments.

Additionally, packages should enter the tunnel with enough spacing to allow consistent airflow. Once the correct settings are established, operators can document them to simplify future production runs.

STS 1609-3 Applications

The STS 1609-3 can support many industrial and consumer-product shrink-packaging applications. For example, suitable products may include:

• Printed materials and stationery
• Packaged foods and confectionery
• Household and personal-care products
• Pharmaceutical and medical products
• Hardware and small components
• Electronics and accessories
• Retail products
• Promotional packages
• Multipacks and product bundles

Additionally, shrink film can improve product presentation and provide protection from dust and handling. Depending on the application, it can also provide bundling or tamper-evident packaging.

Pairing the STS 1609-3 With an L-Bar Sealer

For automated film sealing, the STS AL-ALC automatic L-bar sealer can feed prepared packages into the STS 1609-3. Therefore, the two machines can form a continuous automatic shrink-packaging system.

Alternatively, lower-volume operations can pair the tunnel with the STS ML1-K semi-automatic L-bar sealer. That arrangement provides greater operator control while still producing professionally sealed and shrunk packages.

In either configuration, conveyor height, product dimensions, film specifications and production speed should be evaluated together.
